A number of years ago I purchased my first 70-200. It was the f/4 non-IS version and I thoroughly enjoyed that lens. I soon felt the need for a faster aperture and purchased the f/2.8 non-IS version with which I was very happy. Image quality was very good and the weight was manageable. However, not long after, I decided to upgrade to the IS version of that lens but was never totally happy with the image quality it delivered, especially at 200mm and wide open.

When the 70-200 f/4L IS was introduced and got rave reviews, I decided to give up the fast aperture and opt for the improved image quality. That turned out to be a fantastic lens and I loved the images it produced. Then along came the new f/2.8L Version II and because of the reviews I couldn't resist. I coughed up the money and bought one.

That was one of my best ever purchases. In a word, this lens is spectacular in every way. The AF is super fast and accurate and the image quality it produces is simply outstanding. At any focal length and any aperture. I am in love with this lens. I believe it is as sharp as my 300 f/2.8L IS and my 500 f/4L IS. Yes, you read that correctly.
